JOS. P. BARBIER, OF WAYNE, OHIO.

EARTH-EXCAVATOR.

Specification of Letters Patent No. 22,847', dated February 8, 1859.

To all whom 'it may concern.

Beit known that I, J osnrrr I). BAKKER, of IVayne, in the count-y ofAshtabula and State of Ohio, have invented newand useful Improvements inEarth Scrapers and Excavators; and I do hereby declare that thefollowing is a ful] and complete description oit the construction andope ation ot' the same, reference being had to the accompanyingdrawings, making part ot'this specification, in which- Figure l, is aside view-Fig. 2, is a` top view. Fig. 3 is a vertical section, showingthe apron elevated, and Fig. 4, is a vertical section, showing the aprondepressed.

The nature of my invention relates to the method herein described ofarranging and adjusting the apron, so as conveniently to discharge theearth taken up, at any desirable point.

The sides of the scraper and excavator are made of plank, and are shownat A, Figs. l and 2. The handles A, extend backward, and are formed fromthe same piece oit' plank as are the sides A. At the forward end, thereare two straps of iron, one upon each side of the side pieces-the samebeing seen at B, B, projecting forward and downward, and fittedtoreceive the journals C, C, ot the wheels C', C. rIhe pieces B, B,articulate upon the rod D, which extends from one side plank to theother. A screw thread is cut upon each end of this rod, and a nut isplaced both inside and outside of the side pieces A, and thus the piecesA are secured between them. These nuts are seen at E, F. The pieces B,B, are secured at the inner end, by a pin F. A plank Gr, is

Jlaced between the side ieces at an angle of about forty-five degrees, alittle back of the middle of the pieces A, and held in place by therodsH, H. Upon the inclined plane thus formed rests the apron I. This ishinged at the bottom as seen at I. Lying immediately behind this apron,is a bent lever J, having its fulcrum upon the rod H. rIhis lever isdouble, and its long arm-s are curved as seen at J.

The rear end of the scraper and excavator, is supported by two wheels KFig. l, placed immediately below the handles A. These are supported bythe arms L. These arms articulate upon the pin L and can be set in anydesired position, and secured by the pawl and ratchet M, N. The pawl N,is kept in place by the spring O, which may be applied in anyconvenientmanner.

The blade I), which penetrates the earth, is placed at the lower edge ofthe inclined plane G, to which it is properly secured by bolts. The endsare also turned at rightangles and aresecured to the side pieces A. Ateach end of the blade, is attached a colter O, which serves to dividethe earth taken up from that which remains.

il" hat I claim as my improvement and desire to secure by LettersPatent, is-

The manner of arranging and adjusting the apron, and operating the sameby means of the bent levers J, for the purpose of convenientlydischarging the earth taken up at any desired point as set forth, andused in connection with the adjustable wheels as herein described.
